WOODWARD 5501-467 Simplex Power Supply Board

Overview

The WOODWARD 5501-467 Simplex Power Supply Board operates on both 220 VAC and VDC input. It is designed for use in the MicroNet Simplex and MicroNet Plus chassis, though it functions only in a simplex configuration. In the MicroNet Simplex chassis, the board is classified as high voltage for both AC and DC.

Power Specifications and Differences

The power specifications differ between the two chassis types:

• MicroNet Plus Chassis:
  • Max Input Power: 1250 VA
  • Max Input Current: 6.7 A
• MicroNet Simplex Chassis:
  • Max Input Power: 1062 VA
  • Max Input Current: 5.9 A

LED Indicators on Front Faceplate

The 5501-467 board includes four LED indicators to monitor power supply health:

• OK LED: Indicates normal operation.
• Input Fault: Signals an issue with the input.
• Power Supply Fault: Shows a failure in one of the power converters.
• Overtemperature Fault: Warns of overheating.

If the Power Supply Fault LED lights up, check for a short circuit. After removing the short circuit, if the board doesn't return to normal operation, replace the power supply.
